GAS-BURNER.

Application tiled .Taming-j 19, 1888. Serial No. 261,250. (No model.)

.To all whom t may concern:

Be it known that I, WILLIAM P. IIBnnNs, of the city of Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Gas-Burners, of which the following is a specification.

This invention relates to a burner which is more especially designed as a natural-gas burner for heating-stoves, furnaces, steamboilers, dce., although it is equally desirable for burning artiicial gas.

The object of the invention is to construct a simple burner of this character which can be easily adjusted to regulate the size of the flame, and in which the quantity of air admitted to the burner for promoting combustion can also be conveniently regulated, so as to obtain the desired proportion of gas and air to eifect a perfect combustion,'whether a large or small quantity of gas is consumed.

Theinvention consists of the improvements which will be hereinafter fully described, and pointed out in the claims.

In the accompanying drawings, Figure l is a side elevation of myimproved burner. Fig. 2 is a longitudinal sectional elevation thereof. Fig. 3 is a side elevation of the open frame or cage arranged at the upper end of the mixing-tube, and to which the Haine-de fleeting disks are attached. Fig. 4 is a horizontal section in line r oc, Fig. 2.

Like letters of reference refer to like parts in the several figures. p

A represents the gas-supply pipe, which is screw-threaded at its upper end and provided with an annular or cup-shaped chamber, B, having at its lower end a screw-threaded collar, I), iitting over the screw-threaded end of the supply-pipe A. The upper closed end of the chamber B is provided with an annular row of openings or perforations, Z9', through which the gas escapes.

The volume of gas that is delivered to the burner is controlled by the aggregate area of the gas-escape openings b. In order to regulate the volume of gas in accord ance with the requirements of the particular use to which the burner is applied, several chambers B are provided for each burner, differing in the number and size of the gas-escape openings b', so that the volume of gas supplied to the burner can be regulated by selecting a chamber B having the proper aggregate area of escape-openings- Then a greater volume of gas is required to be delivered to the burner, the chamber B is removed and another one put in its place having a larger aggregate area of escape-openings, and when the volume of gas is to be reduced a chamber having a smaller escape-area is substituted.

C represents a mixing-tube arranged above the chamber B, and in which the gas and air are commingled before passing to the burner proper at the upper end of this mixing-tube. The latter is connected with the chamber B by means of an open frame, I), consisting of an upper ring or collar, (l, en circling the lower end of the mixing-tube, alower ring or collar, d', embracing the upper contracted portion of the chamber B, and four upright arms, d2, connecting said rings. The upper ring, d, is provided with an internal screwthread, which engages with an external screw-thread, c, formed at the lower end of the mixing-tube, so that the latter can be adjusted vertically in said ring to increase or diminish the space between lthe lower end of the mixing-tube and the upper surface of the chamber B, and thereby regulate the supply of air to the tube. The lower ring, d', is preferably secured to the upper reduced portion of the chamber B by a set-screw, c.

Gis an open annular frame or cage secured to the upper end of the mixing-tube C, and composed of a cap, g, a ring or collar, g', and four vertical arms, g2, connecting said ring and cap and arranged at equal distances apart, the spaces between the arms and the cap and ring forming exit-passages for the gas and air contained in the mixing-tube.

II I represent the deflecting plates or disks of the burner proper', surrounding the cage or open frame G, and attached, respectively, to the cap g and ring g. The upper deflecting-disk, II, is provided with a collar or sleeve, h, which surrounds the cap c, and is secured to the latter. by a set-screw, 72,.

The lower deflecting-disk, I, is preferably made concave or conical, and is provided with a collar, i, embracing the ring g', and is adjustably secured thereto by a set-screw, /,so that upon loosening' the latter the lower dc IOO fleeting-plate can be raised and lowered on the ring g', to increase or reduce the distance between the delecting-plates and regulate the size or thickness of the flame. This adj ustment may be effected by means of the upper deliecting-disk, H, if desired; but I prefer to secure the upper disk permanently and adjust the lower disk.

By rendering the upper disk, H, removable, as illustrated, an upper deiiecting-plate of greater or larger diameter may be attached to the burner, according to the Volume or width of flame desired. This construction also permits the cages or frames D G, at opposite ends of the miXing-tube, to be readily removed and be connected to a longer or shorter mixingtube, as may be necessary to suit the requirements of each case.

When an increased supply of gas is admitted to the mixingtube C, it becomes necessary to increase the air-supply and also the space between the burnerdisks H and I, through which the mixture of gas and air escapes, in order to properly burn the gas. These adjustments can be readily made by turning the mixing-tube in the collar d, so as to increase the distance between the lower end of the tube and the perforated top of the chamber B, and by lowering the disk I, so as to increase the llame space. By providing the burner with these adjustments a small burner can be used for ordinary purposes, and when an eXtra consumption of gas is required the burner can be readily adjusted for such increased supply.

It is found in practice that when a small quantity of gas is consumed and the flame is quite low the latter has a tendency to shoot downwardly into the mixing-pipe and not appear at the upper end of the burner. To avoid this, a horizontal diaphragm or disk of wire cloth or gauze, j, is arranged in the mixingtube near the upper end thereof, as shown in Fig. 2. This diaphragm is preferably provided with a marginal flange, j', which bears against the walls of the mixing-tube and retains the disk j in position by its friction.

I claim as my inventionl. The combination, with the mixing-tube G and the open frame or cage G, secured to the upper end thereof and composed of a cap, g, a ring, g', and connecting-arms g2, of an upper deflecting-plate, H, secured to the cap g, and a lower deilecting-plate, I, made vertically adjustable on the ring g', substantially as set forth.

2. The combination, with the mixing-tube C and the open frame or cage G, secured to the upper end thereof and composed of a cap, g, a ring, g', and connecting-arms g2, of an upper deiecting-plate, H, secured to the cap g by a set-screw, h', and a lower delecting-plate,

I, secured to the ring g by a set-screw, i', substantially as set forth.

3. The combination, with the gas-supply pipe, of a gas-chamber having gas-escape openings, an open frame secured to said chamber,

a mixing-tube secured with one end to said frame and made adjustable therein toward and from said gas-chamber, an open frame secured to the opposite end of said mixingtube, an upper detlecting-plate secured to said frame, and a lower deiiecting-plate also secured to said frame and made adjustable thereon toward and from the upper deflecting-plate, whereby the admission of air to the mixing-tube and the size of the iame can be regulated to correspond and produce perfect combustion, substantially as set forth.

Witness my hand this 13th day of January, 1888.
